1. An umbrella device for removing a valve the umbrella device comprising:
- an elongated shaft having a distal end;
a first umbrella comprising a first mesh, the first umbrella coupled to the shaft at or near the distal end of the shaft;
a second umbrella comprising a second mesh, the second umbrella coupled to the shaft proximal to the first umbrella; and
a mechanical drill rotatably coupled to the shaft and positioned between the first umbrella and the second umbrella; and
at least one electrical coil positioned along portions of the shaft at or near the first umbrella and the second umbrella, wherein the at least one electrical coil is/are independently operable to generate a magnetic force upon introduction of a current to said at least one electrical coil.
